HYoRooARsoN STREET-LAMP.

SPECIFICATION forming part of Letters Patent No. 739,711, datedSeptember 22, 1903.

Application filed September 20, 1901. Serial No. 75,753. (No model.)

`To all whom t may concern:

Be it known that I, CHARLES PERILLAT, a citizen of France, residing inBoston, in the county of Suffolk and State of Massachusetts, haveinvented an Improvement in Hydrocarbon Street-Lamps, of which thefollowingdescription, in connection with the accompanyin g drawings, isa specification, like characters on the drawings representing li keparts.

This invention relates to a hydrocarbonburning lamp especially designedfor lighting streets and like places exposed to the weather. Instreet-lights employing a hydrocarbon oil as the illuminant and as nowcommonly constructed and known to me the vaporizer is located in closeproximity to the mantle within the ordinary glass globe or lantern,which is provided with suitable means by zo which access may be hadtothe said vaporizer and mantle. The globe or lantern is located at theupper end of a post, which is of such height as to require the use of aladder in order to obtain access to the vaporizer to light 2 5 the lampwith the usual torch. It frequently happens that when the door of thelantern is opened to light the lamp the mantle is shattered by the forceof the wind, thereby inl creasing the cost of maintaining this system 3oof lighting.

This invention has for its object to-provide a street-lamp of the classreferred to in which the lamp canbe lighted without exposing the mantleto the wind and without the use of 3 5 the ladder usually employed. Forthis purpose I employ a hollow post provided at its upper end with aglass globe or lantern and at its lower end with an enlarged base, whichmay and preferably will be made of suflicient 4o size to contain theoil-tank and vaporizer and in general all the operative parts of thelamp except the burner and mantle, which are 1ocated in the globe at thetop of the post. The hollow post contains within it means for lightingthe gas or vapor as it issues from the burner within the globe at thetop of the post, which means is under the control of the operator fromwithin thehollow base of said post. Provision is made within the hollowbase, whereby the kerosene or other liquid hydrocarbon used may beprevented from freezing in extremely cold weatherfas will be described.These and other features of this invention will be pointed out in theclaims at the end of this specification.

Figure 1 is a partial section and elevation of a hydrocarbon street-lampembodying this invention; and Fig. 2, a section on the line 2 2, Fig. l,looking toward the left.

In the embodiment of the invention herein shown a represents the globeorlantern,which is located at the upper end of the hollow post b,provided with a substantially large base c.

The post h and base c may be of metal and made in Aone or more parts, asdesired, and

the globe a is-made of glass and is provided with a suitable cap d,which may be of metal.

In accordance with this invention the hollow base e contains within itthe main operative parts of the lamp proper-namely, the

`oilsupply tank e,- vaporizer f, connected thereto by a pipe g, providedwith a valve h; a vapor-mixing chamber i, into which the vapor isdischarged fromV the vaporizer and wherein said vapor is admixed withair supplied by the air-tubesj; a heater or burner lo, l

which is connected with the mixing-chamber il by a pipe Z, provided witha shut-olf valve The vaporizer may be of anysuitable or desiredconstruction, but preferably that shown in United States Patent No.654,669, granted to me July 3l, 1900, it being provided with a'needle-valve n, by which the quantity of vapor discharged into themixing-chamber may be'regulated. The mixtureof vapor and air isconducted from the chamber t' to one or more burners o, located withinthe globe d, and in the present instance two burners are shown, (seeFig. 2,) which are connected to the mixing-chamber il by a pipe p,extended through the hollow post and intothe hollow base, wherein it maybe provided with a shut-off or valve q. n

The burners'o ma;7 be of any suitable or usual construction and are`provided with mantles s, such as now commonly employed with this classof lamps.y As above stated, provision is made forigniting the vapor atthe y I i y burners from within the hollow post, and in the presentinstance I have shown one means for accomplishing this result.

In the present instance the mixing-chamber 7l has connected to it a pipe3, extended up into the globe a and provided with branches 4, whichcooperate with the burners 0.

l The pipe 3 is located adjacent to and substantially iu line withthe'vapor-conducting pipe p, and the branches 4 are similarly locatedwith relation to the burners 0, as clearly shown in the drawings. Thepipe 3 and its branches 4 are provided with a line of perforations 5 onthe side adjacent to the pipe p andthe burners o, so that vapor issuingfrom the said perforations may be ignited and the iame .employed to heatthe pipe p and also ignite the vapor at the burners. The pipe 3 may andpreferably will be provided with a shut-off or valve 6, which isaccessible from within the hollow base of the lamp-post.

To facilitate an even distribution of the vapor throughout the length ofthe tube or pipe 3, which latter in practice may be of considerablelength, the latter may be separated into an upper and a lower chamber'by a flange 7 on a tube 8, which latter is located within the'v lowerpart of the tube 3 and is of smaller diameter than the same. The tube orpipe 3 lnay be made in three parts, as represented in Fig. 1. By meansof the smaller tube 8 a portion of the vapor may pass directly up intothe upper chamber or portion of the tube 3.

The base c may be provided with a suitable door 9. (Shown in its openposition in Fig. I.)

The perforated tube or pipe b constitutes one form of igniter, which islocated within.

the hollow post and is accessible from within the base thereof.; but Ido not desire to limit my invention to the particular form shown.

When the lamp is not in use, as in the daytime, the valves 6 q areclosed, while the yvalves m h may be closed or open, according tocircumstances, as will be described. As-` suming the valves m h closedand that it is desired to light the lamp, the operator iirst opens thevalve m and heats the vaporizer by means of a hand-torch or in any othersuitable or usual manner. The valve his then opened, which permits theoil contained in the tank c under pressure to flow up into thevaporizer, wherein it is vaporized, and the needle-valve n having beenopened the vapor passes into the mixing-chamber t', from which it passesthrough the pipe Z into the heater or4 auxiliary burner la and fromwhich it issues, being ignited by the hand-torch. As soon as the flameappears at the auxiliary burner they valve 6 is opened and vapor fromthe mixingchamber passes into the tube or pipe 3, from which it issuesthrough the perforations 5 and is ignited'by the hand-torch.

When blue flame appears in the globe or lantern a, the valve q is openedand vapor from the mixing-chamber passes up through the tube p to themantles, where it" is' ignited by the flame of the igniter. The valve 6is then closed. It will thus be seen that the gas issuing from theburners and mantles located in the globe or lantern at the top of thepost may be ignited from within said post, thus enabling the lamp to belighted without the necessity of opening the globe or lantern, therebyavoiding the danger of shattering or breaking the fragile mantles by thewind, also dispensing with the use of the usual ladder now commonlyemployed and enabling the lamp to be lighted in a minimum time.

It is to be 'observed that the auxiliary burner-k heats the interior ofthe hollow post while the lamp isin use, as at night, and in extremelycold weather the interior of the hol- -low post may be maintainedsufficiently warm Y during the day-time to prevent the oil in the l. Ina lamp ofthe class described, the combination of a hollow elongatedpost, a globe or lantern at the upper end of the post and having lthechamber within the globe communicating with the chamber in the post, aburner in the globe, a burner-tube extending from the chamber in thepost to the burner in the globe, means for igniting the globe-burnerextending from the chamber within the post to the chamber in the globe,a liquid-supplying receptacle in the post remote from the passage ofcommunication between the post and the globe, a vaporizer, an auxiliaryburner and a mixing-chamber all within the post and adapted to supplyvapor to the burner within the globe, substantially as set forth.
